231 13. Commercialized household waste drying systems Household waste drying is an innovative technology that has never been used before for the management <strong>and</strong> treatment of household organic waste. There are no EU <strong>and</strong> International reports showing that household waste dryers have been used in the past in either small or large scale for the treatment of this type of waste. An extensive World Wide Web research revealed that there are some commercialized household organic waste drying systems that could be used as a single device without being part of a wider waste management concept. No publications have been found though showing the research results of the use of these household appliances. It must be mentioned that all the household waste dryers found were for indoor use only <strong>and</strong> made in Korea mainly. This Section aims to provide a brief description of the existing commercialized household waste drying systems. 13.1. Loofen household waste dryers Loofen Lee Co., Ltd was established in 2003 in Korea. The company has been developing innovative household <strong>and</strong> commercial waste drying systems since then. A series of household <strong>and</strong> commercial waste drying systems have already been constructed <strong>and</strong> have obtained many national certifications. The company’s waste dryers though have not been widely distributed internationally up until now. The company has created many series of household waste drying models with different capacities <strong>and</strong> capabilities but they all have the same philosophy. They all use heated air for the drying process. In the following picture, some of the 5L capacity models are shown: Picture 79.: Loofen company’s household waste drying systems, 5L capacity (Loofen., 2010) The following picture shows some of the 4L capacity models distributed by the company:
